I would guess that it is reasonably modern. Looking at the screw type closure, I doubt seriously it is pre-prohibition.
After prohibition, a statement that begins "Federal Law Prohibits Reuse of This Bottle" had to be embossed on all liquor bottles. This regulation remained in effect until 1964. If this is not on your bottle I would guess 45 years old max. The distillery name was likely on a stuck on paper label.
